I was aware of the "hav-a-hart" traps for larger animals such as skunks, raccoons, etc, as these are an effective alternative for people who don't have other means of exterminating these pests; and typically these creatures typically don’t take up residence in one’s home as do mice and rats. They pose more of a nuisance to gardens and shrubbery. But a humane trap for disease carrying filthy rodents is beyond me.
